Maw of Souls - Mythic Keystone Strategy Guide

Welcome to the Maw of Souls M+ Guide. This guide will assume that you have a basic understanding of the mechanics of the trash and bosses that are outlined in our Maw of Souls Dungeon Guide. This Guide will go over common routes to achieve trash count, indicate difficult trash packs at high keystones and provide tips for affixes.

Composition

When doing high keystones in Maw of Souls, we would recommend the following things in your composition:

Interrupts - Interrupts will be required on multiple mobs to prevent heals and CC effects on the party. At least two short cooldown (15 seconds) kicks are necessary.

AoE Stun - Some of the deadly trash in the dungeon is stunnable.

Route Advice

The most general way to achieve mob count in Maw of Souls is as follows:

Pull all the trash in the first area, before King Ymiron.

In the boat -- pull the pack of Garde des âmes saumâtre, the Vivelame maudit par les flots on the left and the addition pack on the right at the first interaction. Follow the corridor and pull all mobs on the left side of the boat which includes the Grimewalker.

On top of the boat -- pull all mobs on the left side of the boat, plus the single Champion helarjar on the right.

There are two minor skips that allow you to skip trash packs. For every pack you skip, you'll have to make up the mob count somewhere else.

Before Ymiron

Players are able to skip the first two mobs of the instance by hugging the left wall and running along the skeletal bones.

Walk up the slope to the left and along these bones to skip the first two mobs.

After Ymiron

As keystone levels continue to increase, the Marin de la garde de nuit becomes incredibly dangerous and Le Marche-crasse has a lot of health. This is made even worse on Fortified weeks. It may be worth to save time and deaths by using an Invisibility Potion.

King Ymiron

King Ymiron will become incredibly lethal on high keystones and have a high chance of killing your Tank:

Sombre entaille deals an incredible amount of damage, and Tanks should aim to have cooldowns for every cast.Protection Warriors can use Renvoi de sort every other Sombre entaille. This will deal a massive amount of damage back to Ymiron!

The most dangerous Sombre entaille is the one during the Plaie cast since adds will be hitting the Tank as well.

Cris des morts can be dispelled if a player is hit, but remember this will do a large amount of damage as well.

Vivelame maudit par les flots can be deadly for tanks as they will cast Attaque très pernicieuse with no warning and bypass physical reduction abilities. You'll have to do your best to guess when this ability is coming in.Molosse éthéré will jump to a random ranged target and dealing damage. Try to have ranged stack close and use a defensive cooldown as multiple leaps will probably kill the player.

Players should aim to hit 30% as the cast of a Lanterne des ténèbres ends and burst it down before the next cast.

There isn't much space to work with in the ship, so tanks should try to kill the creatures next to the wall to make sure there's still room for both players and the mobs to stand.

Helya

For Phase 1, its important to note that only Tentacule destructeur are affected by Tyrannical and neither are affected by Fortified.

The Tentacule destructeur will apply Rupture rapide a DoT that will automatically stack to 3 on its own, which causes it to do a massive amount of damage to the Tank. Use cooldowns liberally on this ability.

Tentacule destructeur are the highest priority target as each one needs to die before the next one spawns.

The Tentacule avide have very large hitboxes and can be cleaved very easily.

This greatly increases the chance of future Tentacule destructeur spawns in the front center which allows for easy cleave.

There is no location at the front of the ship where more Tentacule perforant can break through.

Make sure to interrupt every Torrent. A two-person interrupt rotation is sufficient (~15 second cooldown each).

Transfert-like effects often fail on this section of the boat. Make sure that you can quickly run out of any Rugissement corrompu casts in your direction.

Due to the nature of the ship, Explosive orbs can spawn almost anywhere on the ship in Phase 2.

In Phase 1, both types of tentacles can spawn Explosive orbs and ranged should take care of the ones away from the Destructor Tentacle.
